2003 Volkswagen Jetta wipers, windshield & visibility problems

We purchased a brand new 2003 VW jetta in june of 2003. I have had no problems with the vehicle until yesterday, 11/28/04. We could smell something "hot" and burning. The drivers seat caught on fire from the heated seats, there is a hole in the seat and my boyfriend burnt his hand. Within minutes of that happening, the passenger side door window just fell down. I've never seen anything like this before. Somehow, the window is no longer in it's track.

Sun roof drain clogs!!! No direction in manual for cleaning nor warning that it can happen. I found nearly three inches of water in the floor and water all over the interior fuse block. My concern is fire related. Corrosion can lead to high impedence connections and after water intrusion I have no idea how safe my electrical system is. This is the second or third incident and I finally found out what was causing the problem by doing research on the internet.
